Has anyone ever worked with this "Fax to usb" devices? Dr Shimanov bought this, I tried to install this on his pc using several installers that it comes with (none worked, all failed , send help) the installer seems like it makes it appear on device manager for a brief second, but then it goes away, and never comes back, regardless if we unplug it and replug it multiple times, and even if we get it to install, no idea how this works, it even comes with windows 98 installers, so you can get an idea how old it is lol, any ideas what I can try here? 🫠 this is the device > https://www.amazon.com/dp/B09YPRRCZ4?starsLeft=1&ref_=cm_sw_r_cso_cp_apin_dp_K2KGA2NY2QHGH9FC72Y5

A white cable (likely RJ-11 or USB) is coiled beneath the disc; no visible physical damage or error codes are present on the hardware.

this is what comes up for a brief second, when we try installing it

**Device Manager — Conexant USB CX93010 ACF Modem Properties** The General tab shows **Device type: Modems**, **Manufacturer: Conexant**, **Location: Port_#0004.Hub_#0005**, and the Device Status field reads **"This device is working properly."** — indicating no error codes are present. The device is listed under the **Modems** category in Device Manager on what appears to be a Windows 10 system. Two red arrows in the image point to the modem entry in the device tree and to the Device Status section of the properties dialog.

but then it goes away, and never comes back

Tech B 2024-03-07 15:08

did you get any messages about the driver not working or something like that? Maybe try disabling memory integrity and reboot to see if it helped

Tech A 2024-03-07 15:09

yeah, left is expectation, right is reality

A Word document shows a "Device Driver Installation Wizard" dialog for a **USB Data Fax Voice Modem**. The document's reference image shows the expected result as **SUCCESS**, while the actual wizard dialog overlaid on screen displays a result of **FAILURE** for the same device. Both dialogs display the message "Device driver installation complete. Installation results."

his pc is windows 10, which is supposed to work... at least based on the installer

Tech A 2024-03-07 15:10

Tech B 2024-03-07 15:10

Tech A 2024-03-07 15:13

yeah, this Dr buys some good stuff, I installed a sensor for him recently, just look at the install folder

No error messages or diagnostic indicators are visible.

# Fix USB Fax Modem Driver Installation Failure on Windows 10

## Problem
A Conexant USB CX93010 ACF Modem (USB fax device) fails to install properly on Windows 10. The device briefly appears in Device Manager during installation showing "This device is working properly" status, but then disappears and never returns even after unplugging and reconnecting. The Device Driver Installation Wizard consistently shows "FAILURE" results despite multiple installation attempts using various installers included with the device. The device comes with legacy installers including Windows 98 versions, indicating older hardware compatibility issues.

## Resolution
1. Disable Windows Memory Integrity protection and reboot the system
2. Attempt driver installation again after the reboot

Note: This device has known compatibility issues with modern Windows systems. Amazon reviews indicate inconsistent functionality, and the device may simply not work reliably on current Windows 10 installations despite advertised compatibility.
